Why Session Overlaps Matter
When two major stock exchanges are open at the same time, the combined order flow from both regions increases market depth. More buyers and sellers competing simultaneously means tighter bid-ask spreads and more efficient price discovery.
For equity traders, the London–New York overlap (roughly 9:30 AM–4:30 PM London time) is the most important. It represents the single highest-volume period of the global trading day. Major index moves, earnings reactions, and economic data releases during this window tend to have the largest and most immediate price impact.
For forex traders, overlaps are even more critical. The EUR/USD pair, for example, sees its highest daily volume during the London–New York overlap because both the eurozone and the US dollar economy are active simultaneously. Trading the same pair during the quiet Asian session typically means wider spreads and less momentum.
The Tokyo–London overlap is much briefer — as little as 30–60 minutes depending on the season — but it matters for JPY pairs as London dealers begin pricing in Asian session moves when they arrive at their desks.
